EX-99.1

San Diego and Vancouver, British Columbia, May 13, 2014 – Sophiris Bio Inc. (NASDAQ: SPHS) (the “Company” or “Sophiris”), a biopharmaceutical company developing a clinical-stage, targeted treatment for the symptoms of benign prostatic hyperplasia (BPH) or enlarged prostate, today announced financial results and recent key operational highlights for the three months ended March 31, 2014.

“During the first quarter we continued the enrollment in our first Phase 3 clinical study of PRX302 as a treatment for the symptoms of BPH,” stated Randall Woods, president and CEO of Sophiris Bio. “We are on track with completing enrollment of patients in the Phase 3 trial during the second half of 2014.”

At March 31, 2014, Sophiris had cash, cash equivalents and securities available-for-sale of $40.3 million and working capital of $33.4 million. Sophiris expects that its current cash, cash equivalents and securities available-for-sale as of March 31, 2014 will be sufficient to fund its operations for at least the next 12 months.

The Company reported a net loss of $8.5 million ($0.52 per share) for the three months ended March 31, 2014 compared to a net loss of $117,000 ($0.04 per share) for the three months ended March 31, 2013.

The Company recognized no license revenue during the three months ended March 31, 2014. During the three months ended March 31, 2013, the Company recorded as revenue a $5.0 million non-refundable milestone payment from Kissei upon the achievement of certain development activities, as such milestone had been achieved during the three months ended March 31, 2013.

Research and development expenses were $6.8 million for the three months ended March 31, 2014 compared to $2.9 million for the three months ended March 31, 2013. The increase in research and development costs was attributable to an increase in the costs associated with the Company’s first Phase 3 clinical trial and an increase in manufacturing activities for PRX302.

General and administrative expenses were $1.4 million for the three months ended March 31, 2014 compared to $1.2 million for the three months ended March 31, 2013. The increase is primarily due to the increase in stock-based compensation expense from the three months ended March 31, 2013 to the three months ended March 31, 2014.

Interest expense was $0.2 million for the three months ended March 31, 2014 compared to $0.4 million in the same period in 2013. This decrease was due to a reduction in interest expense related to the Company’s promissory notes with Oxford Finance.

Interest income of $17,000 was recorded for the three months ended March 31, 2014 as a result of interest earned on cash equivalents and available-for-sale securities.

No income tax expense was recognized during the three months ended March 31, 2014. The $5.0 million milestone payment that the Company recorded from Kissei during the three months ended March 31, 2013 was subject to a 10% Japanese withholding tax. As a result, the Company recorded income tax expense of $0.5 million for the three months ended March 31, 2013.
